Beschreibung
Zusammenfassung:	An improved acoustically and thermally insulating composite material suitable for use in structures such as buildings, appliances, and the interior passenger compartments and exterior components of automotive vehicles, comprising at least one airlaid fibrous layer of controlled density and composition and incorporating suitable binding agents and additives as needed to meet expectations for noise abatement, fire, and mildew resistance. Separately, an airlaid structure which provides a reduced, controlled airflow therethrough useful for acoustic insulation is provided, and which includes a woven or nonwoven scrim. La présente invention concerne un matériau composite amélioré d'isolation phonique et thermique, destiné à des structures telles que des immeubles, des appareils, et les garnitures intérieures et extérieures d'habitacles d'automobiles. Ce matériau est constitué d'une couche de fibres aérodéposées de densité et composition contrôlées, complétées de liants et additifs appropriées pour répondre aux attentes en matière de réduction du bruit et de résistance au feu et à la moisissure. L'invention concerne également une structure aérodéposée capable d'un écoulement atténuer et contrôlé de l'air la traversant, ce qui est intéressant pour l'isolation phonique, et comporte canevas tissé ou non.
